2 - Thermal Energy Storage Thermal energy storage () is particularly suited to air conditioning and industrial refrigeration systems. Usually traditional air conditioning systems operate throughout the day especially during the hottest hours to meet instantaneous demand and remain idle at night. These chillers are designed to meet the maximum daytime instantaneous cooling demand, which only occurs a few days each year. The energy storage system is a flexible and reliable solution for the management of important energy needs. It enables a significant reduction (up to 70 %) to the chiller capacity of machines which have been installed or are to be installed. The capacity can now be calculated according to the total demand in 24 hours and no longer according to peaks of maximum instantaneous cooling demands. The system from ENALpro allows energy storage at night (period of low tariff electricity and lower outside temperatures) and uses it by day, thus permitting significant savings in running costs. Nowadays it has become essential to optimize energy consumption. A modern, eco-friendly company has to invest in technology, optimize product quality and most of all significantly reduce energy costs. AT NIGHT technology enables the storage of cooling at night in conditions of maximum chiller efficiency. BY DAY The energy stored at night is released during the day. Eutectic liquid Thermal energy is stored in a particular liquid called PCM Phase Change Material which has 14 times the storage capacity of water and allows significant savings of costs and space.

These chillers are designed to meet the maximum daytime instantaneous cooling demand, which only occurs a few days each year.

4 TYPES OF STORAGE outside STORAGE UNDERGROUND STORAGE Enal Tank Enal Tank The dimensions of the energy storage tank are calculated based on the thermal performance requirements of the project and for existing plants on the plant space available. The tank may be cylindrical (for service pressures up to 10 bars) or rectangular (concrete and steel) for atmospheric pressure. Tanks can be designed horizontally, vertically and even placed underground. energia alternativa Our technical staff are able to propose and develop the best solution for any specific requirement. _1

5 HOW IT WORKS STORAGE The energy produced by the cooling system at night is stored in the ENAL tank, under favourable outdoor temperatures and low energy tariff conditions. chiller chiller DIRECT PRODUCTION In moments of low energy demand, it is sufficient to use only the chiller. ENERGY RELEASE The energy stored in the ENAL tank is released during the day and the chiller is switched off in this period. chiller chiller ENERGY RELEASE AND DIRECT PRODUCTION During peak hours it is possible to use both the energy stored at night and that directly produced by the chiller.

ENERGY RELEASE The energy stored in the ENAL tank is released during the day and the chiller is switched off in this period.
